Answer / Sukh Beer Singh
The forRoot() method in Angular 4 (actually Angular 2 and up) is used when you need to create and register a service that should be available throughout the entire application, such as a shared service. The forRoot() method typically returns an instance of the service along with metadata about the module it belongs to, which allows Angular to manage the lifecycle of the service properly.
